4 Domestic hot water control
The C203 tries to keep the temperature of domestic hot water at
the designated setting value. This ensures that the temperature
of water from the shower always remains constant. Because of
danger of bacteria, it is recommended that the domestic hot water
temperature is not permanently set below +55°C.

Anticipation speeds up regulation when water consumption
changes by using measurement information from the circulation water sensor. The regulator recognises the sensor and
automatically starts to use anticipation when the sensor is
turned on. You can also stop using anticipation.

In mechanical manual mode the valve’s position is set from the actuator. To
prevent the regulator from changing the position of the valve, the actuator’s
power input must be disconnected.
